[Rails] date problem in ruby

are you saying that time.wday did not work?

$ irb
ruby-1.8.7-p302 > time=Time.new
=> Thu Feb 02 09:11:24 +0000 2012
ruby-1.8.7-p302 > time.wday
=> 4
ruby-1.8.7-p302 > time.month
=> 2
ruby-1.8.7-p302 >

Colin

no, That is working... but i need like this

:bill_date => u.bill_date,

I want to take the day, month,year from this *u.bill_date.* can i get, if
am using like this
*
*
*:day_of_week => Time.month(u.bill_date)
*
*
*
*...........?*

What type is bill_date? Assuming it is a Time or Date object then you want
u.bill_date.month

Colin

colin, The data type of bill_date is *date*

date is not a class type. It could be Date. Do you mean that the
column type in the database is date or that it is a string containing
a date or what? What does it show for the column type in schema.rb?

What happens when you do bill_date.month as I suggested?

By the way please remember to include the relevant parts of the
previous messages in your reply otherwise it is difficult to follow
the thread (particularly for those who may find the thread later and
hope to learn from it). Also please insert your reply at appropriate
point in previous message rather than posting at the top of the new
mail. Thanks.

Sorry i forgot that, i will follow that way in next time....

Thank you

colin, thanks

I got it from this

* :day_of_week =>u.bill_date.day,*
* :day_of_month =>
(Date.new(Time.now.year,12,31).to_date<<(12-u.bill_date.month)).day ,*
* :month_of_year =>u.bill_date.month,*
* :year => u.bill_date.year*
*
*
*
*
*Thank you*

Are you sure that does not give you the day of the month, I would have
expected wday to give day of week, though since you still have not
told use what type bill_date is then we cannot be sure.
As I said above I would have expected day or mday to give the day of month

*Can i use this same way to get the day, month, year from the default field
created_at..**?*
*
*
*i mean *:day_of_week =>u.created_at.day
*
*
*i just tried that but got some error .day.. i think created_at field with
timestamp. so that will be the problem...?*

*thank you*

If you get an error you have to look at it and work out what it means,
which is not always easy but you will get better at it with practice.
It is no good asking for help here and just saying you got some error,
you must provide the details, but first try and understand the error.
Also read up on and experiment with the rails console, it can be very
useful for trying things out, for example:

$ rails console
Loading development environment (Rails 3.1.3)
ruby-1.8.7-p302 > u=User.first
User Load (0.9ms) SELECT `users`.* FROM `users` LIMIT 1
=> #<User id: 1, <snip>, created_at: "2011-11-25 22:01:46",
updated_at: "2011-12-16 15:33:24", approved: true>
ruby-1.8.7-p302 > u.created_at.day
=> 25

Time and Date are quite different. Think seriously on your business need
what
you really need, a Time or a Date.

if you need a _date_ e.g. start_date of a contract, don't use Time, it will
get
confusing when local time gets involved. The concept of

contract_start_date => "1 Feb 2012"

is different from the concept of

contract_start_time => "1 Feb 2012 00:00:00+00"

At contract_start_time (midnight in London) it is still 31 Jan 2011 7pm in
NYC
and the contract has _not_ started yet to NY standards ...

HTH,
